飞行品质监控是分析查找原因、消除隐患、确保飞行安全的有效手段。为了避免人为主观因素对飞行品质监控项目标准制定的影响,提高监控项目预测的准确性,基于着陆垂直加速度的截尾正态性和风险度量理论,提出了民用飞机着陆垂直加速度标准的诊断模型,该模型通过风险极大化的思想,得到了着陆垂直加速度的次优监控标准。通过对某航空公司的数据进行数值试验,给出了某高原机场和某普通机场的着陆垂直加速度超限标准和一些相关结论,结果表明,监控项目标准具有动态性,该诊断模型是合理有效的,除了用来诊断着陆垂直加速度,此诊断模型还可以运用到满足截尾正态分布的其他参数上。
Flight operational quality assurance is an effective means to analyze the causes,eliminate hidden dangers and ensure flight safety.In order to avoid the influence of subjective factors on the overrun standards,and improve the forecasting accuracy of overrun event,based on the truncated normal property of landing vertical acceleration and risk measure theory,the standard diagnostic model of civilian aircraft landing vertical acceleration is proposed,the model obtains the suboptimal standard by the idea of maximum risk.According to the experiments of an airline's flight data,the overrun standards of landing vertical acceleration and some relevant conclusions of a plateau airport and a normal airport are presented,the results show that the overrun standards are dynamic and the diagnostic model of this paper is reasonable and effective.In addition to landing vertical acceleration,this diagnostic model can also be applied to other parameters,which meet the truncated normal distribution.
